What is a Tricuspid Atresia?
Tricuspid Atresia is a congenital heart defect in which the tricuspid valve does not form, preventing normal blood flow from the right atrium to the right ventricle. The right ventricle is often underdeveloped, and babies usually have an opening between the atria, such as an atrial septal defect, to allow blood to reach the left side of the heart. Other defects, including a ventricular septal defect or patent ductus arteriosus, may also help maintain blood flow to the lungs; symptoms and treatment depend on the amount of pulmonary blood flow and associated heart abnormalities.
What is the Importance of Timely Treatment?
Timely treatment is critical in d-TGA because inadequate mixing of oxygenated and deoxygenated blood can cause severe oxygen deficiency soon after birth. Immediate stabilisation, maintenance or creation of adequate blood mixing, and definitive surgical repair can improve oxygen delivery and reduce the risk of serious complications. Lifelong congenital heart follow-up is also important after repair because some patients may develop valve, coronary artery, rhythm, or other cardiac problems later in life.
What are the Common Symptoms of Tricuspid Atresia?
- Cyanosis: Bluish or greyish skin, lips, or nails may appear soon after birth because of low blood oxygen levels.
- Breathing Difficulties: Rapid or difficult breathing may occur when the baby has inadequate oxygen delivery or associated heart problems.
- Poor Feeding: Babies may have difficulty feeding, tire easily during feeds, or take longer to feed.
- Weak Pulse: Reduced oxygen delivery and impaired circulation may contribute to weak pulses.
- Rapid Heartbeat: A fast heartbeat may occur as the heart attempts to maintain adequate circulation.
- Poor Weight Gain: Babies with significant congenital heart disease may have difficulty gaining weight and growing normally.
Causes and Risk Factors of Tricuspid Atresia
Causes
- Abnormal Heart Development: TGA occurs because the major arteries do not develop with their normal connections to the ventricles during fetal heart development.
- Genetic Factors: Genetic or chromosomal factors may contribute to some congenital heart defects, although the specific cause of d-TGA is unknown in most cases.
- Developmental Factors: Complex interactions between genetic and environmental factors may influence heart development.
Risk Factors
- Maternal Diabetes: Poorly controlled diabetes during pregnancy has been associated with an increased risk of d-TGA.
- Family History: A family history of congenital heart defects may increase the likelihood of certain congenital cardiac abnormalities.
- Genetic or Chromosomal Conditions: Some congenital heart defects occur as part of genetic or chromosomal conditions.
- Pregnancy-Related Factors: Certain maternal health, environmental, medication, or nutritional factors may contribute to congenital heart defect risk, although most cases of d-TGA do not have an identifiable cause.
Latest Research and Technologies in the Treatment of Tricuspid Atresia in India
- Current TGA care focuses on early prenatal and newborn diagnosis, rapid stabilisation, advanced echocardiography, specialised neonatal cardiac care, and timely surgical repair. Fetal echocardiography can help identify d-TGA before birth, while newborn pulse oximetry and postnatal echocardiography support diagnosis and assessment of associated defects and cardiac function. For d-TGA, the arterial switch operation (ASO) is the most commonly used definitive repair and is generally performed early in life. In critically cyanotic newborns, prostaglandin therapy may maintain ductal blood flow, while balloon atrial septostomy may improve blood mixing when necessary.
Treatment options for Tricuspid Atresia
Ductal Stenting: In selected babies, a stent may be placed in the ductus arteriosus to maintain pulmonary blood flow and reduce the need for an early surgical shunt.
Systemic-to-Pulmonary Artery Shunt: A surgical shunt may be created to increase blood flow to the lungs when the baby's anatomy requires additional pulmonary blood flow.
Balloon Atrial Septostomy (BAS) : A cardiologist performs a BAS (also known as a Rashkind procedure). They insert a thin, flexible tube called a catheter into a blood vessel, usually in the groin, and thread it up to the heart.

Pulmonary Artery Banding: If too much blood is reaching the lungs, pulmonary artery banding may be used in selected patients to control pulmonary blood flow and protect the pulmonary circulation.
Bidirectional Glenn Operation : In this staged procedure, the superior vena cava is connected directly to the pulmonary arteries, allowing blood from the upper body to flow to the lungs without passing through the right ventricle.

Fontan Procedure : The final major stage of palliation connects venous blood from the lower body to the pulmonary arteries, allowing blood to reach the lungs without ventricular pumping. Selected patients may undergo a fenestration.

Heart Transplantation : Rarely, transplantation may be considered when the heart becomes severely weakened or when the Fontan circulation fails, and other treatments are unsuitable.

- Clinical assessment:
- Prenatal Assessment: Routine pregnancy ultrasound may raise suspicion of tricuspid atresia, followed by fetal echocardiography for detailed assessment.
- Medical and Birth History: Assessment includes pregnancy history, delivery details, cyanosis, breathing, feeding, and associated congenital conditions.
- Physical Examination: Evaluation of skin colour, breathing, heart sounds, pulse, blood pressure, oxygen saturation, and signs of poor circulation.
- Electrocardiogram (ECG): May provide information about heart rhythm and electrical activity.
- Blood Tests: Blood gases, glucose, electrolytes, blood counts, and other tests may be used during neonatal stabilisation and treatment.
- Imaging Tests:
- Fetal Echocardiography: Provides detailed prenatal assessment of the heart chambers, valves, great arteries, septal defects, and blood flow.
- Transthoracic Echocardiography (TTE): The primary postnatal imaging test used to confirm tricuspid atresia and assess ventricular size, associated defects, pulmonary blood flow, and cardiac function.
- Chest X-Ray: May provide information about heart size and pulmonary blood flow.
- Cardiac CT: May provide detailed anatomical information in selected complex cases or when additional anatomical assessment is required.
- Cardiac MRI: Can assess ventricular function, pulmonary arteries, blood flow, and other structures during later childhood or adult follow-up.
- Cardiac Catheterization: Measures pressures and oxygen levels within the heart and blood vessels and can also be used for selected interventions.
- Three-Dimensional Imaging: Advanced imaging may assist detailed anatomical assessment and procedural planning in selected complex cases.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive rehabilitation services designed to support Tricuspid Atresia patients in India. These services include:
- Cardiac Rehabilitation: Selected children and adults may benefit from structured rehabilitation according to cardiac function and treatment history.
- Gradual Physical Activity: Increase activity according to oxygen levels, ventricular function, symptoms, rhythm status, and congenital heart specialist advice.
- Paediatric Developmental Support: Children with complex congenital heart disease may require developmental assessment and early supportive interventions.
- Occupational Therapy: Selected children may benefit from support with age-appropriate functional activities and independence.
- Exercise Assessment: Older children and adults may undergo exercise testing to guide safe physical activity.
- Long-Term Congenital Heart Follow-Up: Regular specialist assessments help monitor ventricular function, oxygen levels, rhythm, Fontan circulation, liver health, exercise capacity, and other potential complications.
- Medicines used in Tricuspid Atresia depend on the baby's anatomy, oxygen level, pulmonary blood flow, ventricular function, and treatment stage. Doctors may give prostaglandin E1 soon after birth to keep the duct open and support pulmonary blood flow. Other medicines may help manage heart failure, fluid retention, blood pressure, or abnormal heart rhythms. After staged surgery, some patients may require medicines such as diuretics, rhythm-control medicines, antiplatelet therapy, or anticoagulation depending on their circulation and individual risk.
